如何在Android中使用xml菜单更改操作栏中搜索框的提示文本？

我正在开发一个Android应用程序。在我的应用程序中，我正在使用

AppCompactActivity

使用操作栏。我成功实现了操作栏中的搜索框。但我有一个小问题。我想更改搜索框中的提示文本。请查看下面的屏幕截图：

这是带有搜索项的my menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item android:id="@+id/office_action_search"
        android:orderInCategory="97"
        android:title="Search"
        android:icon="@android:drawable/ic_menu_search"
        app:showAsAction="always"
        app:actionViewClass="android.support.v7.widget.SearchView" />
</menu>

如何更改搜索框的提示文本？

请添加以下内容

<style name="SearchViewMy" parent="Widget.AppCompat.Light.SearchView">
    <item name="searchHintIcon">@null</item>
</style>

@空的

您可以使用方法

setQueryHint

自定义

SearchView

的提示

按如下方式修改代码：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.office_main_menu, menu);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        SearchView search = (SearchView) menu.findItem(R.id.office_action_search).getActionView();
        search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));
        search.setQueryHint("Your custom hint");
        search.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                //tabLayout.getTabAt(0).select();
                return true;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                return false;
            }
        });
    }

    return true;
}

我做的有点不同。在我的例子中，我使用SearchView的setText方法。SearchAutoComplete如下所示：

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.menu_search, menu);

    final SearchManager searchManager = (SearchManager) getContext().getSystemService(Context.SEARCH_SERVICE);
    final MenuItem searchItem = menu.findItem(R.id.action_search);
    final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));

    SearchView.SearchAutoComplete searchAutoComplete = (SearchView.SearchAutoComplete) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    searchAutoComplete.setText("Type your music...");

    // rest of code 
    .....
}

将android:title=“Search”更改为其他字符串我尝试过。但它不起作用。那么我要把它分配给什么呢@无效的

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.menu_search, menu);

    final SearchManager searchManager = (SearchManager) getContext().getSystemService(Context.SEARCH_SERVICE);
    final MenuItem searchItem = menu.findItem(R.id.action_search);
    final SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));

    SearchView.SearchAutoComplete searchAutoComplete = (SearchView.SearchAutoComplete) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
    searchAutoComplete.setText("Type your music...");

    // rest of code 
    .....
}
